(5) sunflower seed after threshing falls in screen box from support grid together with impurity, ground floor sieve by magazins' layout larger for volume out, the impurity of small volume and sunflower seed drop down onto second layer sieve, and after second layer sieve shake screening, the impurity of small volume is separated; Through the screening of two-layer sieve, sunflower seed falls into sunflower seed delivery chute; While the threshing of sunflower head, complete machinery clean sunflower seed, screening efficiency is high;
(6) sunflower seed is pushed to the second lifting device by the auger in sunflower seed delivery chute, and sunflower seed is lifted to eminence by the second lifting device, is convenient to pack operation;
(7) sunflower seed sack-filling device is " V " type structure, has two discharging openings, goes out to be provided with catch at discharging opening, and when a discharge hole for discharge pack, another discharging opening is plugged, and in the outer end of discharging opening, socket sack is ready; Two discharging opening dischargings in turn, achieve and uninterruptedly, continuously pack operation, substantially increase operating efficiency.
The utility model, by the application of the plant equipment of the operations such as feeding, threshing, screening, pack, achieves the mechanization flow process operation of sunflower threshing, reduces the labour intensity of workman's operation, shorten the sunflower threshing time, improve operating efficiency.
